Job description

Remote | UTC+8 | Core collaboration hours: 1:00–7:00 PM Manila Time

Salmon is a technology-driven financial company building a banking and lending platform across Southeast Asia, starting in the Philippines. We combine global fintech expertise with deep local market knowledge to make financial services simple, accessible, and useful for millions of people across the region.

7M+ app downloads. 2M+ monthly active users. 7,000+ partner stores. US$310M+ raised from leading global investors.

Manila-based, globally distributed, and hybrid-first — our team spans 45+ countries.

If you want to solve complex problems at scale and impact how millions of people access and manage money, come build with us. Southeast Asia's fintech moment starts here.

About the role:

You’ll build the microservices behind Salmon’s core banking products — reliable, scalable systems supporting how millions of Filipinos manage their money.

What you’ll do:

• Build scalable microservices in the JVM environment using Spring Boot, within the Core Banking Development Team.
• Work in an event-driven architecture grounded in domain-driven design (DDD) and eventual consistency.
• Collaborate across engineering to develop and scale Salmon's core banking and partner platforms.

What you’ll own:

• Build and maintain reliable, scalable microservices in the JVM environment using Spring Boot.
• Design event-driven services applying domain-driven design (DDD) principles and eventual consistency.
• Build and maintain APIs and services that support core banking products.
• Contribute to internal SDKs and frameworks that streamline how teams build on shared services.
• Integrate with partner platforms and external services at scale.
• Support the development and scaling of banking and partner platforms as Salmon grows.

What makes you a strong fit:

• 3+ years of software development experience in the JVM environment, with strong Java skills (Kotlin is a plus).
• Experience using Spring Boot in a microservices environment.
• Experience working in an agile setup with continuous deployment and delivery.
• Solid understanding of event-driven architecture, domain-driven design, and eventual consistency.
• Experience with containerization and orchestration — Docker and Kubernetes preferred — in a cloud environment (AWS preferred).
• A collaborative mindset and willingness to share knowledge across the team.

What we offer:

Ownership and flexibility

• Fully remote work with core collaboration hours from 1:00 to 7:00 PM Manila time (UTC+8)
• Company-provided tools and equipment

Health and time off

• Medical insurance support for you and your family through co-funding or reimbursement, depending on your location and subject to policy limits
• Access to an internal mental health support specialist
• 22 vacation days, Philippine public holidays, and 15 sick days

Growth and team experience

• Opportunities to learn and share your expertise through internal expert meetups, external conferences, speaking opportunities, and industry publications
• Company-sponsored trips to Manila to meet and work with your team in person
• High-performing teams can earn a dedicated beach house week in Southeast Asia

We believe strong teams are built by people with different backgrounds, experiences, and points of view. Salmon is an equal opportunity employer, and we make hiring decisions based on skills, experience, and potential.
